2 Claims. (Cl. 240-818) The present invention relates to portable lightsflange 30 on the reflector 29 and holds the same and, in particular tolights with magnetic atin position. A guard member 32 is formed intachment devices whereby they may be mounted tegral with the attachingring 3|. 1 e on any magnetic permeable surfaces. The casing Iii has anopening 33 therein It is an object of the invention to provide suchthrough which extend two wires 38 and 39 con- 5 a light that is compactand durable in-construcnected to the opposite ends of a source of elec-*tio-n; that will spread the light Well; that may ric l supply. .A il 34i Wr pp d about th easily be disassembled for repairs; and that is coreI3 of the spool I2 with'a suitable number inexpensive to manufacture. ofturns.

The light consists of a casing ID that is tubu- It has the conventionalcontacts, one at the bot- 20 lar in shape with an upper threaded flangeII tom which will engage the spring plate 24. and. thereon. Within thiscasing is fitted a spool I2 the other enga e soc et ember The consistingof a magnetically permeable core I3 current from the power sourcethrough wires 38 and two insulating end members I4 and I5, reand 33 isdirectly ted to these two 816- 5 spectively.
